Singer FKA Twigs has been recovering after having six fibroid tumors removed from her uterus in December.

“I am a very private person as u all know and I have gone back and forth in my mind whether to share that this year I have been recovering from laparoscopic surgery to remove 6 fibroid tumors from my uterus,” the 30-year-old revealed in an Instagram post on Wednesday, adding that two of the tumors were the size of “cooking apples,” three the size of kiwis and one the size of a strawberry.

A nurse told her that with the weight and size of her tumors, it was like Twigs was six months pregnant.

According to Dr. Shirazian, symptoms can range from “completely asymptomatic to heavy bleeding, pelvic pain, pelvic pressure, urinary frequency, sometimes even constipation and rectal pressure” — depending on the number and location.

Many women simply think they’re just putting on weight, so fibroids can go undetected, the doctor said.

As for Twigs’ situation, Dr. Shirazian said it’s “pretty common,” and that an apple-sized fibroid would be moderately sized at about five to six centimeters while a strawberry-sized fibroid would be around two centimeters.

“But once they’re all together it’s increasing the total size of your uterus, so the symptoms that you’re feeling are that bulk pressure because now, instead of having a small uterus the size of your fist, imagine your fist, plus two apples and three strawberries and everything else,” the doctor told us, adding that she’s seen women who have uteri that appear to be nine months pregnant.

Dr. Shirazian says fibroid tumors are typically not fatal, and that Laparoscopic surgery, which Twigs got, has really good recovery rates.

“I tried to be brave but it was excruciating at times and to be honest I started to doubt if my body would ever feel the same again,” Twigs wrote alongside a video of herself dancing on a pole. “I was so scared, despite lots of love from friends and family I felt really alone and my confidence as a woman was knocked. but… today whilst dancing with Kelly at the choreography house I felt like my strong self again for the first time in a while and it was magical.”

Twigs thanked her body for healing and called other women who suffer from fibroid tumors “warriors.”

“And with this I let go of the pain… love always twigs,” she ended the post.
